The Trend Of High Barrier Packaging

It has been widely used in the preservation and flavor separation of food, cigarettes, beverages, as well as moisture-proof packaging in the chemical, pharmaceutical, electronic, and military industries.
Single layer PVDC film is produced by bi-directional stretch blow molding, which has shrinkage, barrier, and water resistance properties. It does not decompose under microwave heating conditions and is widely used as household cling film; Multi layer extrusion of PVDC and synthetic resins such as polyethylene (PE), polypropylene (PP), and polystyrene (HIPS) is used for packaging vacuum dairy products, jams, and other products. Its tensile properties are good and suitable for larger volume packaging; The composite sheet of PVDC, PE, and polyvinyl chloride (PVC) is suitable for packaging drugs that are easily hygroscopic and volatile. Many domestic research institutions and manufacturers are focusing on the research of PVDC and other resin composite laminated film technology, as well as the high-temperature resistance technology of composite films.
High barrier packaging has a good development trend in China due to its advantages of freshness. There are also two main reasons for this. Firstly, China's milk production is mainly in the north, while milk consumption in the south is higher than in the north, making room temperature packaging of milk particularly urgent. Secondly, with the improvement of national living standards, the demand for fruit juice drinks and tea drinks has been increasing year by year. Therefore, the demand for sterile packaged food is constantly increasing. Aseptic composite material processing in China, except for multinational enterprises. In the next few years, the production and quality of sterile composite packaging materials in China will greatly improve, thus breaking the monopoly of bankrupt enterprises. The development prospects of sterile packaging are very promising.
